摘要
为了提高预警信息发布的效率,按照将预警信息优先发送给最需要的人群的设计思想,提出了运用基于预警信息内容、特定区域和人群的靶向技术进行精准发布的推送策略。首先,通过分析预警信息发布技术研究现状及存在的问题,从时间、区域、人群三个维度研究预警信息精准发布的关键技术;然后,利用地理信息系统(GIS)的区域搜索技术,设计了针对手机短信、手机APP等多渠道靶向发布的处理流程和技术方案;最后,提供了针对主要发布渠道的核心算法示例,通过算法快速过滤,使经过研判的预警信息优先发送给重点区域人群。该靶向技术在省级预警发布业务中得到成功应用,验证了该方法的可行性。与采用群发或广播的发布策略相比,该方法降低了预警信息发布阻塞或推送缓慢的概率。
In order to improve the efficiency of early warning information release, according to the design idea of sending firstly early warning information to the most needed crowds, a push strategy for accurate release with targeting technology based on contents of warning information, particular regions and crowds was proposed. Firstly, the research status and existing problems of early warning information release technology were analyzed to obtain the key technologies for the accurate release of early warning information in three dimensions: time, region and crowd. Then, the processing flow and technical solutions for targeted release in multi-channel such as mobile SMS and mobile app were designed by using the regional search technology of Geographic Information System (GIS). Finally, some core algorithm examples for main distribution channels were proposed, and the early warning information was analyzed and judged through rapid filtering of the algorithm,then be sent to the crowds in key region. The feasibility of the proposed method was verified through successful application of targeting technology in a provincial early warning release business.Compared with the release strategy like group sending or broadcasting, the proposed method reduces the probability of block ed push or slow push of early warning information.
